Online dating sites such as Match.com and eHarmony draw millions with a promise of replacing chance meetings on the office elevator with a targeted computer search for a soul mate. Now there's Prescription4Love.com, a dating Web site ''for people with special conditions.''
Launched in 2006, Prescription4Love was created by Ricky Durham in memory of his brother, James Keith Durham, who died in 2004 after a 15-year battle with Crohn's disease.
''He couldn't meet people,'' remembers Durham. ''He had a colostomy bag, so he didn't feel comfortable meeting people.'' Things might have been different, Durham believes, if his brother had been able to find somebody who shared - and understood - his illness. The Web site allows users to do just that by searching according to different conditions, such as AIDS, infertility and obesity.
