If possible, I think to have a separate category for Writers only (Articles, Stories, Proofreaders, etc.) would be extremely beneficial.
This would be an excellent category for the genuine sellers of these items to showcase/show off their writing skills/talents. It would give those buyers/lurkers (not logged in but the forum) an opportunity to see what the writers really have to offer.
Unlike every other gigs here, writers must be able to write. Researching the gig pages do NOT give me an accurate summary of the writer’s ability. I buy tons of writing/editing/proofreading gigs here. I do realize there will be some growing pains as there are translators/voiceover artist among many others who also offer proofing as an add-ons.
