anyone ever convert a mtb frame to a road bike? i'm thinking of turning an mid-90's steel frame into a beater bike....wondering if there are any unforseen problems with swapping out the mtb parts for road fit, etc. let me know of any experienced problems. thanks

I think where you'll have the most trouble is making road components fit a mtb frame. Things like seatposts, bottom brackets and forks are the first things that come to mind. MTB parts tend to be larger and heavier. Getting smaller road components to fit would be your biggest roadblock. However, several road forks come in 1 1/8 now. You could make it work with some research, I'm sure.

Front der is usually top pull on a MTB and bottom pull on a road bike.

Handlebar clamp diam is different so you can not just put on road bars.
Done it twice, works fine, no problems... makes a good commutercory

You can't make a good road RACER out of an MB, but you can make a fine everyday, ride-around bike. Components aren't a problem--you don't need road components (why would you change the seatpost and BB?). Leave the driveline as it is unless you need higher gearing (you probably don't; most road bikes are geared too high for most riders).
Tires are the obvious change, and make the biggest difference. I'd go with something in the 1.25-1.5 range, not superskinny 1.0s. Existing wheels are fine.
Bars are up to you--you may need a new stem if you use drops, but you may not want drops at all. I rarely use the drop part of my handlebars even on my road bikes (again, we're talking about a beater/everyday rider, not a racer). Ride it a few times before you start fooling with gearing. You may find that the existing gears are all you need. If not, a cassette swap is easy and cheap.
This just isn't as complicated as people seem to want to make it. You're not going to build a C40 out of an old Diamondback or whatever, but you can certainly build a very useful bike. I did several 50-70 mile pavement rides on mine back when I couldn't afford a roadie, and still use it for a 22-mile commute. And I have room for fenders!
This is a very common question, especially on the Cross Board...Marketing Dept

I pained over the decision for almost a year. When I finally did it, I was happier than I would have imagined.

Started off with a retired Litespeed Hiwassee. Added Ultgera STI shifting, kept the STX crank, lost the granny ring and added a 48 outer ring. Up front, I bought a Surley rigid fork with suspension geometry (necessary).

This ride is just awesome. The one bike for almost any occasion. Any chance I get I share a pic of it.

On my lunch hour, I am able to do a few miles of road work, ride down a flight of steps to a greenway, cut through the woods on single track and repeat the process back to work. FUN!

One warning, you may need a shorter (much shorter) then what you may be used to on a road bike. You will not be as fast as a 53X11 20mm tired road bike (unless you the engine are).
