Introduction to is a well tuned installation of the free open-source software.
Get Commenting
It is free to chat publicly with your family, group or co-workers on your own group. Also see the Messaging User Guide for specific instructions.
Choose Any Topic
Enter a group name in the 'AtomJump' search box. If it is a general topic, you can chat with the public there, or you can share the name of your group with your friends. You can make up a new group without signing in.
It's live
It all takes place live, across over 260,000 groups (and counting).
You can share a group with your friends via e.g. SMS by tapping the 3 circle 'share' icon in the top right hand corner. Or you can copy the URL [group] in the browser address bar, which is unique to your group. E.g. london․atomjump․com for London talk. When you're chatting you can also use the special @ tag at the end of a word to provide a fast link to another group forum eg. london@.
Start a business
Accepting payments from other users off a forum is as easy as writing e.g. 'pay 5 dollars to me' in a message (this will accept payments in $US). Your AtomJump email address must match your Paypal account email. AtomJump take no commission, but standard Paypal charges apply. For UK users, you can also write e.g. 'pay 3.50 pounds' to accept British pounds.
Private Forums
Private forums at xxxx․atomjump․com are purchased at $US10 / year per page. You can set a password on a forum for a private discussion within a family, team or company. With this, you have any volume of messages and any number of users. Note: If this is a trademarked name, we may require proof of ownership.
