I can’t sign into meebo
If you're unable to sign in to meebo it can mean a number of different things. Please check the following:
1. Check your network connection. [this probably won't be the case]
2. Make sure your username and password for the particular network you’re accessing are correct and match. [we have it saved, so this probably won't be the case]
3. You may have logged into a network and not been properly logged out…wait about 5-10 minutes and try again. [this might affect us, unfortunately - we probably need to make sure to log out before signing in at the other machine]
4. Try using another browser.[i think this means closing that window and opening a new browser window]
If you've checked the above mentioned possibilities, send an email to comments@meebo.com
