this seems like a good idea but honestly idk
it would be relatively difficult t code something like that, I suppose. and while there is and issue of loosing members in roleplay due to you being supposedly inactive it would help rp leaders greatly, but is it really necessary when if the Rogers stick around till when your on at the same time, you could /possibly/ explain yourself? tho again at the same time timelines are relatively a major issue, and establishing you have what and they have what might be able to help out their situation. some members of rp will lea,ve just because the leader isn't online, unfortunately. And time zone is entirely out of the equation for the most.
really even with an activity. Ad while it might be able to prevent some users from disappearing from your rod, it won't prevent all. some are, as I've found with my castroval so far, members are there because th e leader is wOw so COOL ammAzing wow
