I see that on some people posts, they have a picture of themselves holding a fish, I was wondering How to do that, cause I would like one of me?

Those lil' pics are called "Avatars". Here are a few meanings:

1) The incarnation of a Hindu deity, especially Vishnu, in human or animal form.

2) An embodiment, as of a quality or concept; an archetype: the very avatar of cunning.

3) A temporary manifestation or aspect of a continuing entity: occultism in its present avatar.

Most BBS' let you put a small avitar by adding it in your profile. Sometimes having an Avitar must be earned.

Not sure how to get one on this site. Read the FAQ's perhaps.

Do a search on avatars, and it will be explained to you a few times.

Flymaker, that about sums it up.

One requirement.....to post a pic of you holding a fish....you must catch a fish....
