Very frequently I see the phrase or variation on it of
“I can not link the screenshot because I’m a new user”
in bug reports.
So I suggest that you alter the default new user settings to allow them to link their screenshot etc so you get as much information as possible in the reports they submit.
If you are concerned about off topic posts etc you could trial this for a short time and monitor it.
I think it will also be good for new users who want to post into fan-works areas as well as bug or suggestions etc to encourage them to stay engaged with the forum/community.
