Following a suggestion from Sven not so long ago I've added a couple of things to the VAR chapter of the User's Guide: an explicit reference to the SVAR addon, and an account of the current state of the diagnostic tests for VARs. If anyone would like to check them over that would be good. There's still a couple of "todo" sections in that chapter (as in several other chapters, though the Guide is now 387 pages). If anyone felt like having a go at filling in the blanks that would be good too! Allin
