I don't know if this is a bug or part of the forum software.. Basically I can edit PM's after sending them, is this a bad thing?
It's meant to be like that. Saves people sending more than one message because they left a letter out of one word. Neat.
But it should probably be changed, shouldn't it? Because the way it currently works allows you to edit PMs long after the conversation has advanced, so there is potential for scamming. It'd be fine if you were able to edit for up to 15 minutes after it's been sent though.
The number of edits I do makes me worried only because when I edit its like 5 minor changes over the course of 3 separate edits.
It's deliberately not restricted. It may be worth considering, but hasn't been an issue. We can't read other people's conversations. Is there not a view history button if it's been edited?
