That's very odd. Email is supposed to be more reliable than the Postal Service. First, check your junk or bulk folders. If it's nowhere to be found click here to login. You will get a warning message stating that you need to activate your account first along with the option to resend the activation link.

You are out of luck! Just kidding ;) Click here and you'll get your password via email.

From my account panel. Obviously, you have to be logged in.

Most probably your browser is not set to accept cookies. To enable cookies:

• Internet Explorer - Select "Internet Options" from the Tools menu. Click on the "Privacy" tab. Click the "Default" button (or manually slide the bar down to "Medium") under "Settings". Click "OK".
• Safari - From the Safari menu, click "Preferences". From the "Security" tab, under "Accept Cookies", click to select "Always" or "Only from sites you navigate to". Click "Close".

From my account panel. The new email address does not become effective and does not replace the old one until you confirm it. You may resend a confirmation email for the new address as many times as you wish or you may cancel your change of email request from my account.

Nothing's simpler. Just login and click invite in the upper right menu. Whenever the invitees register, you'll become pending friends until they confirm your friendship.

Currently you may search by name & email, project names & project descriptions. You may use filters to get more relevant results.

Click on the "be friends" option whenever you see it in a profile. A request will be sent to that person and he/she will have to confirm your friendship. While your friendhip is pending you have the ability to cancel your friendhip request. Pending friendhips are indicated by red pic borders and by a red letter "P".

Red borders or the red P mean that the friendship is pending. A friendship becomes permanent only when aknowledged by both parties.

No. That's displayed only on your page.

On your page you will see a link that allows you to upload the photo. If the size requirements and file type are correct after the loading bar disappears you'll see the resized photo on your page.

There are two types of projects: open and closed. You'll become a helper of an open project as soon as you join it. In a closed project you'll have to wait for administrative approval. While you wait, you will see your join request as pending in your projects list.

One hundred sounds like a very round number.

The option is found at the bottom left of the my projects page.

You may change your project name only while you are the only helper. Once more people join your project the name becomes uneditable.

Projects are deleted automatically whenever they become empty. If you insist on deleting your project, you may delete all helpers and then leave the project although that would be quite difficult if your project has 10000 helpers!

Only other admins (seen on the right side of the project page) may extend administrative privileges, so you have to bribe them generously ...

On their profile page you'll see the option under their pic. You may not block your friends. Still, if you decide that a friend deserves to be blocked you must first end the friendship and then apply the block. You may see a list with all the blocked people in your privacy panel.

Blocking someone minimizes that person's chance of interacting with you. Blocked people won't be able to see your profile and won't see you in search results.

No. Never.
