Installing a portal

I have a few questions about a portal.

I started looking at it because it would be good to have a list of most recent messages, think members would like that. I can also put some links for other websites on which would also be good.

Is installing a portal free? or do you need forumotion points for that?

Will it not interfere with my domain name as I have a domain name bought elsewhere.

Is it easy to try it out and if I don't like I can uninstall it and still have my forum like normal?

The portal is free. No need for points.
Will not interfere with your domain name and is reversible if you don't like it.

Thanks David (again!) all the way from Australia. I'll better get on with it then.

No problems
