I want to link another thread on another web sight to a thread on this web sight can I do that? if so how. Thanks:unsure:

you could just copy and paste the web address to a new thread ... like so ...

Louisville Marine Aquarium Society :: View topic - new frags ... ready in 2 weeks (http://www.lmas.org/index.php?name=PNphpBB2&file=viewtopic&p=6608#6608)

You can also use the link button. Copy the address of the site you want to link and click the icon at the top of the reply box that looks like a blue circle with a paper clip on it. This also lets you type a word or two, highlight it, then click the link button and paste in the address. This makes the words clickable to that link.

if you use the linkback button (and click LinkBack URL) at the top of the thread it will give you a link in a little popup window

here is the button

Thank you all I think I got it. Trying to give some other reefers links to get here so they can see how great it is..
