Thanks for the suggestion. The website is long overdue for a frontend overhaul, but I'm not really that good at frontend design. I also am rather busy with my other projects at the moment, so I don't have the time to improve this one. At the moment it's functioning quite well by itself.
If you allow me I could design a rough template for a new site and share it with you. As already mentioned, this project has great potential and all it really needs to grow is more available work, which can be solved by using different language and terminology on the landing page. I can do that for you.
