Idea: Allow adding a forum link to the giveaway list

How about allowing giveaway creators to add a forum link which will be shown alongside private giveaways when viewing their profile?

The link would normally be to the original topic (start of train, mass giveaway, ...). Completely optional, of course (I'm sure some gifters hiding games won't want the location to surface), but it would both be a way to advertise certain giveaway topics (which is normally only done with bumping) and also to add some accounting, to reduce somewhat the 'you're only doing private giveaways, you must be part of a CV group' attitude.
