Thread:Project:Support desk/New Section to Talk page is not visible

I'm new to wiki editing and know next to nothing on the technical side, although I have read a considerable amount about procedure and etiquette. I would like to contribute more, but I run into editing issues every time I try to contribute. I know four programming languages and this Wiki is totally baffling me.

I posted to the talk page on the regular public English wikipedia.org on an article about Marcus Luttrell (http://en.wikipedia.org/wiki/Talk:Marcus_Luttrell), and I cannot for the life of me figure out why it is not visible on the page. Also, when I try to sign it with Rpm5099 (talk) 00:41, 29 June 2012 (UTC) it does not get processed for some reason. I have spent considerable time and stubborness trying to figure out why my contributions clearly show in my history but the section I created is not visible on the page. If someone could throw me a bone here, I'm so sick of wasting time trying to figure out why nothing ever works correctly on wiki's for me. If there is a good resource for someone with a very strong background in programming, GUI's, html, web services, etc but f'n hates wikis please point me in that direction. And if you can tell me specifically why my comment is not showing up on that talk page I would greatly appreciate it.
