Welcome back. It is good that you have resumed this commitment. The board index provides links to a great number of learning resources, including those right on the .com domain. Depending on your preference, you could learn from primarily digital sources, such as Memrise, which has been especially recommended for building vocabulary. In terms of print, Oxford Russian Grammar & Verbs and similar books lay out a great deal of information on the mechanics of Russian. Put emphasis on grammatical education when starting out, and learn to recognize both the spoken and written language. Most importantly, make a long-term habit of studying and learning.

Будьте как дома.
