How do i check if the user is part of a group

[iadmirevb]

Hello,
I've created a forum and inside the description i added a html code that embed a flash palyer. The code works great!

<div style="border:0px solid red;margin-top:5px;">
<embed
src="/flv_mediaplayer44/player.swf"
width="350"
height="20"
bgcolor="#E1E4F2"
allowscriptaccess="always"
allowfullscreen="true"
flashvars="file=/media/fileoftheweek_indi.mp3"
/>
</div>

I want to take it one step higher and i want to add a code that checks if the user is part of the registered group. If he is, then i show the code for the flash player.

Is this feasable?

Thanks
Marco
