Hello, Howtosig! I noticed that you seem to be having some trouble with the signature coding — don't worry, it happens a lot. You only need to type one thing:
That's it. Just those four tildes. They automatically add your name and the time you made your post, so you don't have to type any of that yourself!
If you notice that someone is consistently using their signatures incorrectly (i.e. they're typing something like ~~~~[name], etc.), display this on their talk page.
For users who are not signing their posts at all, you can use Template:Howtosig2.
