some ppl might find this information useful: when you "ignore" someone who made a thread, you no longer see messages by that person, but threads that person created also disappear. so this can be used as an unorthodox "hide thread" mechanic.
This is what I have been using as I like the mobile version of the site. The site wouldn't be so bad if it wasn't for the endless mega threads and OTs that the moderation team refuse to move to the community sides. :(
