Like trade chat and help chat, communication through Global Chat can get out of hand during Feats. I propose creation of a temporary Feat chat during the Feats for the purpose of achieving Feats. It is more efficient that way, too!
the temporary chat is an interesting idea! i had a similar idea for an announcements chat channel that could be used for feats but also group badges and parties and such.
That way the players who want to work on the feats can work together on them without spamming global chat and/or regular chat interfering with us seeking players to help on feats.
It's not temporary although I think it just might fit the bill.
Since it's not an admin-created channel, you'll have to join the group, but given the number of re-occurring medium/large rock Glitchen, there's only a couple hundred players that will generate most of the content and traffic.
It's a blank slate at the moment, so let me know how you feel about it- if it seems like it will work, I'll cross-post to the general forum.
