I am webmaster of the following sites:
SPD Life - spdlife.org is the first website ever dedicated to adults with Sensory Processing Disorder. I launched it back in December of 2008, and it has been a work in progress ever since.
SPD International - spdinternational.org was founded initially by my good friend Michelle Morris in 2005. In June 2010, I took over the site at her request, and launched a support forum setup using MyBB, featuring multiple forums for discussion, a wiki, gallery, member blog area, and a chat room.
SPD Parent SHARE - spdparentshare.com was also founded in 2005 by Michelle Morris, and is home to the SPD Parent SHARE Host Community. It is also an awesome place for resources and articles for parents of SPD children. Michelle offered to make me the webmaster in the fall of 2009, and I immediately went to work and redesigned the site.
There is at least one other project that is currently underway, but for now, that is the list of sites I am running. Please feel more than welcome to visit any one of them today!
If you are looking for a good Yahoo based support group, I also am a moderator and/or administrator on the following groups:
SID-DSI AllAboutKids - awesome SPD parenting support resource
SPD Adult SHARE - just like AllAboutKids, except this one is for adults with SPD
SPD Life (group) - the original Yahoo group for the site, still around since Aug '08
SPD College Life - the only group specifically for college students with SPD
SPD Michigan - the only group specifically for SPD families in Michigan
I am on or running other groups as well, but those are the highlights. While these groups are still functional, I still recommend going the route of SPD International, as that is where I am switching the majority of the focus.
