New Rules! - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

As of December 2006, the RF Cafe Forum T-Shirt Contest rules have been changed. Rather than just require an entry in a contest area, I will note contributors for each month, and then randomly select one or more people as winners. Doing so rewards contributors to the forum community.

Thanks to those who participate!

Are questions considered a contribution or is only the act of answering other peoples questions?

Greetings darcyrandall2004:

There is no trademarked formula being applied, but I take comments, questions, and answers into account when picking a winner for the contest. Comments and answers get more weight than questions when it comes to a single thread, depending on the content. For instance, if someone posts a question and then the thread continues with the original questioner continuing to respond to answers with more questions, that does not weigh as heavily as the contributor that keeps giving answers.

That's not to say questions do not count - they do, but I look at the overall effort that is put into participation, since it is the purpose for awarding prizes. I typically give away four prizes each month - two on the forums and two from a random selection amongst people who order my spreadsheets and Visio stencils. Depending on what the winners choose for a prize, it costs between around $60-$90 per month (about $700-$1,000 per year). That's a significant chunk of change for an operation like RF Cafe, so I cannot just hand stuff out to everyone who posts.

I do value everyone's participation. Since its inception about seven years ago, the raison d'etre for RF Cafe has been to service the RF community and foster interaction between engineers, technicians, and hobbyists. So far, it is working pretty well. Thanks to everyone for helping to make RF Cafe a success.
