This serves as a general thread for assisting users in knowing how to tag posts properly. Please view the "help:tags" wiki page for more help on this matter.
Taking a moment to also bring to attention a particular issue: Please do not use rule34.xxx tags outside of the permissible instances noted in the wiki. Rule34.xxx's tags are horrifically inconsistent, so when it comes to copying tags from posts to tag your edits and such please use only the danbooru/gelbooru tags of the post in question, thank you.
