My two €-cents:
I have a principle never to rep anyone who I have seen begging the rep, be it in a sig, included in a post or in a visitor or private message sent to me. However good posts you make, however strongly I feel you should deserve rep from your post, if you have begged it I will not give it. Rep giving should be totally voluntary and transparent.
I also feel no obligation to "return the favor", automatically rep you when (if) you have repped me. The reputation points are not and most definitely should not be the reason we do this, why we are here. We are here out of interest in computing in general and Windows in particular, telling and sharing about our Windows usage, getting help for our issues and helping others to the extent each of us is capable and willing to do. Not counting insulting, racist or discriminating posts, the rep begging is in my honest opinion about as low as you can go.
I totally accept that you are not interested in my opinion and principles but even so, let me just say this one more time: Please accept that you will not get any rep from me if your sig includes something like "If I helped please rep me" or if you send me a PM linking to your new tutorial and asking me to rep it. No way.
Do a good work, see to that your posts are factual and informative, do not base your advice in "I've heard that...", admit when you do not know something, follow your OPs through their issues until the issue is solved or it is clear that you cannot assist anymore, do not think that you own a thread where you were first to respond but instead allow other members to join in with their sometimes different approaches. The rep will come, it is so profoundly ridiculous to blame the size, shape or style of the rep button for missing rep. If you have earned it, it will come.
