Thanks Zarxrax and everyone else!
Also a while ago I had added a book about the basics of layout & design called "The non-designers design booK", to my Amazon whish list and I received it by post about two weeks ago. Thank you!
Well you guys did it, this was the most generous month in donations since I first put up the donation page

There was approx. 350 euros. It is usually around 100 euros, and it ramped up since March when I posted thanks on the news page I guess more people noticed the donation button

I withdraw the donations each month to a savings account as I rarely buy anything with my PayPal account.
Things are moving forward although slowly. Had one meeting at the bank today and one next week someplace else to get information about setting oneself up as a "independent".
Now I need to create a "business plan". Which means I need to define clearly different sources of income, if there is a "premium" subscription for example, how much it is, whichever extras it entails and need to be devloped need to be clearly defined etc etc.
The problem is right now, I did in fact burn out. I am tired of working in the evenings. I feel like I'm always running after something, it's been months since I've read a good book or watched a good movie at home. The refactoring was a lot more work than I thought. I continue to do some work on it here and there so hopefully when I do get around to fund myself and have this business plan done, at least the new site framework is ready.
So now really my dilemma is that some people I've talked to suggested I go half time and start working on the site, but I'm much more motivated to go the "full monty" and devlop full time for 3 to 6 months. In my mind plan B is not so risky because I'm skilled, I've got a good CV and I think it won't be too hard to get another job, in case it doesn't work out well enough or quickly enough. However it seems there are not structures in Belgium that help you do that. Instead, they have specific plans for people who are *out of job* to start something, and they send employed people to the banks, the latter in addition to business plan, etc. does *not* want you to quit your job (or you have to lie to them).
Anyway.. all these things will be clearer once I get a business plan down.
Thanks to some good tips from Ivan, when I finally get around to fund myself I will improve all the RtK aspects and will have to make Trinity secondary. Trinity could be a huge time sink and at the same time create too little revenue, and I won't be able to make the site viable, and thus eventually the site will completely freeze. On the other hand I think it's possible to improve the RtK part, add more tools (eg. I'd love to finish the RtK primitive kanji search), add some extras for encouraging people to get a subscription and make it worthwhile such as kanji quizzes and tests and mini games... there can be plenty of ideas but with a first deadline of 3 months of fulltime work, there is no room for hesitation.
