According to this post, the IET are "recruiting" TPN (Techincal Professional Network) Executive Committee Members
The article explains what TPNs are, what the IET are looking for, and the benefits - but it does not what is involved, nor the expected time committment.
I'm sure I am not the only one curious, so rather than email IET Towers, I thought I'd ask here :-)
