Paperclip (I'm guessing attachment)
what looks like a gift tag

Is there a key?

Whoops, sorry I didn't see this before.

Paperclip = attachment

"gift tag" = tags, i.e. labels to help people search on a topic. Some people tag their threads, probably most don't, but it is helpful. See the "Tags for this thread" section highlighted in GREEN below on this thread.

Not sure what other icons there are but if you can remember any others lemme know! I hate un-obvious icons, myself.

Thank you!
The only other ones I can think of are the green circles with checkmarks and the exclamation marks on the main forum page.

I clicked one to find out - it adds a subscription to the forum it's next to.

and the exclamation marks on the main forum page.
