comment Unable to open old qgis files into the new version ( 1.8.0)
The easiest thing might be to download QGIS 1.7 from qgis.org/downloads and install it on your home computer (if an incompatibility is actually the source of the problem, that is).

comment How to snap lines to points automatically?
I think that's what GreyHippo means by "doing it manually". Just using the Snapping options, you're going to have to move every dangling node by hand to activate the snapping. Or am I missing something?

comment How to implement multivariate hex bins?
@underdark: I think scuerda is using symbols, judging from their sentence "I have managed to cobble together an approach using QGIS SVG symbols".

comment Does QGIS support vector Rubbersheeting?
Apparently there is a v.rectify function in Grass 7 that can do this using control points: Rubber sheeting in GRASS or QGIS (I guess this question is a duplicate of the linked one?)

comment Reclassification of environmental values
Interpolating censored data like this is quite problematic, IDW is really meant for continuous data. Do you have a particular reason for using that interpolation technique? One possibility to deal with this would be to use nearest-neighbour interpolation to assign data values to locations without observations. Or you could interpolate the midpoints of your category ranges instead of the category codes themselves (so assign your points values of 15°, 45° and 75°, run your interpolation on that, and classify the resulting raster).

comment How can I merge adjacent polygons in a shapefile that have been split at tile boundaries?
You should probably post your solution as an answer and accept that instead of mine. Sticking with the question-answer scheme makes it much easier for others with the same issue to find the solution.

Changed approach to not use `v.dissolve`
