If so, this post from CeCe Moore's blog may be of interest as FTDNA have released a set of new tools for exploring your X chromosome matches.
Your download matches from the Chromosome Browser now contain a chr. 98, FamilyTree DNA's name for your X chromosome data.
Haven't had too much time to experiment as yet, but the "match" criteria seems to be lower than the default setting on GedMatch.
Remember that if you have a tree on WikiTree you can easily see who you contributed to your X chromosome.
Log in, select the person of interest and click on DNA in the menu.
Under each person are several symbols which indicate the type of dna the person has
Y (males only, inherited from their father, and passed on to sons), X for all of us, but for your ancestors, X will only show under those who contributed to the root person's X chromosome, mt for us all, but only inherited from your mother (and passed on by daughters), au for automsomal dna, inherited from all of your ancestors, but significant amounts really only detectable for dna matches back to your ancestors 4-6 generations away.
If you click on an ancestor's Y, mt, au or X symbol as you will be sent to the section of the page dealing with who contributed to the X chromosome of the person concerned, remember to scroll up to see the pedigree again.
