Of course this is my personal comment. I believe that it is the best (unfortunately unknown - or fortunately for me) tool on the market. Forget everything and buy this excellent tool.
I have got several seo software and scripts. None of them come close this little monster if you know how to use it.
You should buy premium/paid scripts to be successful. If you got lots of sites (10-1000), it is a must. Along with a windows vps and using its scheduler, nothing can compare this powerful gem.
Wow, I couldn't agree more with absolutely everything you just said!
And submitter is good for more than just forum profiles. You can buy all sorts of cool addons (or whatever you wanna call them).
And it is always getting improved. Heck, at this point it can do blog posts too, etc.
The tool is rediculously priced (cheap) for what you get IMO.
Also, once you get familiar with submitter (and sheduler) it just gets better and better.
The files are easy as pie to edit IMO, etc. etc.
And once you learn how to used scheduler efficiently, you can easily load up your VPS with enough work to keep it blasting for 24+ hours straight, if not more (depends on how much you wanna do back to back heh heh).
Submitter is a little harder to master than certain other programs, like AMR for example, but once you master it, its crazy powerful. And I have had some GREAT results with it too. Be careful though; you can definitely sandbox your site(s) if you don't use it reasonably.
Lastly, I would say it is probably easier to master than xrumor, and probably less powerful than xrumor (or at least slower, plus it cannot do actual forum POSTS, at least not yet). However, I have not purchased xrumor yet, I am only going off of what I have heard about xrumor.
