Hey,
I don't see the advertisements but may be this is because I am not in a country of target (Ecuador).
I do know that it comes from Nabble and it would cost us 5USD per 10.000 page views to get rid of it, see
http://forum.librecad.org/template/NamlServlet.jtp?macro=remove_ads_pageIf the ads come irritating then I think we should be able to get rid of them, the mayor problem is that they only do amazon payments and I need to see if I can buy this with paypal because this
is where the sponsoring comes in, but I am sure I can figure something out for that..
