Used Laminate Flooring

HI, Our neighbour had to rip up her laminate due to a flood and we took her old boards. Most are in not bad shap but when we layed the flooring we have joints that have abviously swollen and so don't fit as they should.
We have simply put this floor in becasue I am tired of walking on concrete and it doesn't have to wonderful and last for years and years but is there some sort of repair I can do to use these boards?
I was thinking that I could cut the lip off the lock and glue the pieces down in the spots where there are gaps...do you think this is worth trying or do you have any other suggestions?

 

Is this a case of one man's trash is another man's treasure?

 

LOL...Yeah, I guess...although how much of a treasure is yet to be determined!
I just hate to see things go to waste...although you know somethings SHOULD be thrown away...I had hoped these wouldn't.
I am going to tackle it this weekend and see if a little creative cutting will save it for the time being...although I am looking at the possibility of just getting new boards...but you know how it is when money is tight you try to do what you can.

 

If you had a table saw you could probably pull off your idea of cutting the tongue & groove & gluing them. You'll need a very straight cut for that though one which you won't get froma skil saw or jig saw. So if you have a table saw & can set it up so each board is cut straight you should be able to work with it. I'd think at least!
