Not quite what you're looking for, but one thing I've done with my old RMC's is cut out the articles that pertain to my interests, and sort them into binders by subject. This is a huge help in getting to an article for a specific project, or ones I check frequently. I recycle what I don't keep.
You may want to check with any LHS you may have as they do sell them. Perhaps a local school, or an indoor flea market would take them too.
(Haven't gotten up the courage to cut up my larger MR collection yet :))
Modeling whatever I can make out of that stash of kits that takes up half my apartment's spare bedroom.
Now that I have the MR archive, I don't need to keep old physical copies of the magazine around.The local library already has a subscription, so no need to donate my old ones there.What's the best way to pass them on to someone who can make use of them? Maybe find a person who already sells old copies at local train shows and work out a deal with them?
