Hi tax haven and welcome, I can see your signature :tinysmile_tongue_t:
The reason for why you and guest members can't see signatures is to reduce SPAM, it is very common for people to register with a forum, key in a signature and just spam the forums, this mechanism avoid this.
You will need to have 15 posts for your signature to be visible, and bearer in mind, that it takes 24 hours from when you made post no. 15 before it will be visible!
