Sorry, I had to remove the "contact me" feature. 99% of messages received were spam and I got tired of it.
Thanks, spammers! I really don't care what happens after people "stumble upon" my site, and about offers to help me keep visitors on the site. I provide information on the site for free and without adverts. If someone finds the information useful, then mission accomplished. If not, then they are free to leave. I make no money on this site. Just trying to give back a little to the community.
I also don't want to buy dog collars or ray banning sunglasses!
The ones who suffer are the people who had genuine questions about some of the information on here (you can try to contact me on Tindie, see "Electronics Products" page).
So thanks again, spammers! You are the ticks of the Internet!
