Coming soon to Ekaweeka - we're building the most active browsing filters and favorites. Active filters will watch who is making items, who is chatting, who started a group or listed an event etc. etc. etc. I guess it's going to use an algorithm (are we really that smart?!? LOL) which essentially means some things count as more active then others, so you know you can't send your buddy 20 messages to become the most active user of the day or something.
Once it's in you'll see the filter in the users browsing section and as we can a similar filter will be available for items and photos too.
"THAT'S GREAT BUT WHAT ABOUT THE GROUP FORUMS?!?!?!" no worries that's also in the making, takes time you know... go read a magazine or something we'll be done with it shortly.
