You shouldn't post what isn't yours.
I didn't say it was mine
i just posted it here because i use it!!!!!
So link to it in the relevant PbP game that you're using it in, or stick the link in your signature or something.
Also, standard protocol for porting something over from another board requires mentioning that it's made by someone else up front at the top of your post in an obvious manner, rather than down at the end in a half sentence mixed in with the end of the stolen post. You should also get the author's permission to do so in the first place. A link to the original post wouldn't hurt either. Not having these things is bad form at best, and plagiarism at worst.
