I know tutorials have been temporarily suspended due to the spammer issue,
but instead of completely suspending for it everybody,
couldn't you just make it so new member have to wait say 2 weeks before posting a tutorial?
I am sure the spammer account would be revealed and deleted before such a time.
And just to be safe
maybe put a limit to how many tutorials all members can make to one per 24 hour period.
Also, maybe do the same with making new threads in the forum.
Only X every 24 hours?
Just a thought.
