Title
option to remove community from friends list when leaving
Short, concise description of the idea
Add a checkbox to "also remove this community from your friends list?" on the confirmation screen when leaving a community. (Just like the checkbox that appears when you join one.)
Full description of the idea
That pretty much says it, above.
An ordered list of benefits
Saves the user from potential confusion and having to go through the extra step to also remove the community from their friends list. (I've had at least one friend who didn't even realize a community was added to her friends list in the first place, because she blindly clicked past the "Also add to your friends list?" screen when joining the community. She got frustrated when the entries kept appearing on her friends page even after she left the community.)
This option would make the add/remove interfaces more uniform.
An ordered list of problems/issues involved
Can't think of any.
An organized list, or a few short paragraphs detailing suggestions for implementation
Reuse the code from join.bml to make this new option available in leave.bml.
