I am fairly new to the site, & I have 3 questions. (1)is there a consumer guide that has all the add on's broken down into categories such as pistol grips, ra systems, folding sites, stocks, slings, triggers, ect., ect., ect.& with where you purchase them? I know this is a lot to ask & that a lot of the fun is getting there with the knowledge, but I'm in a low paying job & I can't afford to by the wrong gear & just squirell it away. I already have some parts that I know will never get used that cost more than I can afford to waste.(2)how do I add the little creatures to my postings that are available on the site?& (3)last How do I add a phrase at the end of my postings,& an icon on the left like so many others have? I thank all you gear guides in advance, your experience is invaluable to me, & some day I may be able to return the kindness. I've noticed the new guys seem to get a lot of help without being treated in a condescending manner. OORAHHH to you all! The only dumb question is the one you don't ask. That's what one of my drill instructors told us. I am most interested in the M-4 add on's

Welcome aboard, Marine.  I don't know of a consumer guide that lists all the available products, but if you do a search on the tupe of items you want, I am sure the collective wisdom of this site will help with your acquisitions.

If you click on the help button near the top of the page. A window will pop up showing you the info you need to get the creatures in your posts [:-)]

Yes, indeed: WELCOME!
The best way to get the skinny on equipment is to post a question, giving what you want, and what kind of use it'll be put to. You'll get a LOT of GOOD answers  and advice from people who really know their stuff.
