So that extension code is complete, if i use it now, will it damage anything.
About the ip, i heard alot of people in some forums say that its very dangerious for other people to have ur ip addresses, donno exactly why, but it may be related to hacking etc. And besides, why would devs actully not do it, even it does increase security "significantly. Wouldn't little more security over some thing is a good thing. unless it takes alot of work, which i don't know if it does.
About the study etc: As i said i cant just learn every language that comes upon me. Web Designing is not good enough for me, i just have one website with punbb in it, that i want to work on it as a hobby.
And besides, This is a PUNBB SUPPORT forum. which means i can ask support for their Open Source Forums Software. You cant ask me to learn Php, xml (whatever other lang) etc to work just few stuff, that actually other members can find it helpful too.
And about those tutorials, i checked them out as i posted above, but cant understand it cuz, no one talking to me from that internet page, cuz i cant just read the codes if they are written like this means (?>"!£_VQ) i can only learn if there is flash tutorial or which talks LOL. But there isn't. And learning a language takes alooot of time.
