I missed Armed Forces Day (May 18th). Thanks, @RDaneel for reminding me (my paternal grandfather, WWI; my father, WWII, Korea, Vietnam; and my stepfather, Korea, are frowning down on me). So I'm totin' this Parker IMAI K-236 double lockback (similar to a Case Texas Lockhorn, designed by Tom Hart) with SPECIAL FORCES etch, in particular honor of my father, who was in the first class of Army Special Forces members at now-closed Flint Kaserne, Bad Tölz, Bavaria, Germany (when they had to buy their own berets).
Many of us use imgur, although with a paid membership you can attach images. imgur is free and pretty easy. Create an account, upload your images and copy the BBCode. Paste that into your BF text box and voila!
