New member looking for modules

[spacemanspiff79]

Hello...

Bought the vb4 license a few months back, and trying to setup my new forum. I have a few questions if anyone can help me

1) Is there a popular ad management module the community uses which can

- show ads on left or right
- put ads between posts

2) Is there any SEO module other than vBSEO ? I know that VB does SEO links, but i want the category/subcategory name in the url as well. Is there any module which can do that

3) Is there a module for Re-tweeting the post and Facebook-Liking the post?

Finally...i really want to know which anti-spam module works best...spammers have wrecked havoc on my forum with about 1000 registrations and 5000 posts daily. I can simply blow it all up as i haven't really started getting real users on it, but it would be good to know how i can delete multiple users and their posts in one go.

Thanks..
