My tools are free, but I used to ask for donations. Indeed there has been a time when some people kindly donated, but the last one is quite some time ago. Never mind, I understand that, but as there are also some costs involved in maintaining this site, I try to get some compensation by placing advertisements, hoping visitors will find some - or all - of them useful.
