Guild Wars 2

If I post a topic in wvw sub forum but meant to post it in raids sub forum, is there a way to move it?

You can’t move it on your own. Only a moderator can. You can delete your post in the WvW forum and then post it in the appropriate forum. The moderators will then remove the misplaced thread once you delete the post.

Or you can report your own thread, and ask the Moderators to move it for you. Likely, they will, eventually.

Good luck.
