There are a couple of likely reasons for the delay in processing your material. One could be that there are way too many items backlogged already so your material has probably been queued too. Maintainers are subject to the rules and vagaries of life too, unfortunately! The other reason could be that the material you have supplied has been distribution denied by the copyright holder (Ultimate games for example) so it would not be uploaded on WoS. If there is an inordinately long delay, you would do well to get in touch with Lee and check with him.
