hi!!,
i think to start a new community its be a good idea to have a tab where we can have users who usually login around same time as i do,
the logic should be for past 1 week login pattern
or past 7 days login.
1. with 2 hr + - login pattern range
2. may be a customized hr range.
3. the tab can have the pics of the users.
just an idea
dee
