The Bradford Tax Institute has a collection of articles on a variety of topics of how to structure one’s own finances to minimize or nil taxes. The website is geared for laymen.

Also, I found another forum Tax Pro Talk, which is geared to accountants helping each other to handle clients’ cases. The posts can be read by anyone, but one legally can’t join and post questions unless he is an accountant or a professional in the field of finance. However, if you use Google to search the forum for keywords of interest, you can find interesting threads of exchange.

There is also Money StackExchange resource, but I did not benefit from it.
