How to add log in in portal?

Please anyone know how to add log in on portal i did this but doesn't work?
Thanks

You want guests to be forced to login before accessing the portal?
If so, sorry but it isn't possible.

Thanks Typlo not forced but it is much more easy and goodlooking because thousands of forumes have this. Maybe my questiona wasn't clear so i put here pic. this one i am sked to put i portal


Thanks Typlo again

I think I understand you, you want to log in from the portal. Yes, you place the form in a block and it (should) work.

I tried it and it didnt work for me...thats why i deleted it...

Ok thanks AussieJay nevermind
