Nice to hear that Yes, they're accepted, at least since design freeze of whole body replacement (aka something like two-three months before I start manufacturing units that are directly going to pre-ordering people). No, thank YOU The logo for donors/pre-orderers isn't limited to anything, as long as it's doable/feasible, and you're able to provide suitable 2D image of it in the format that I'll announce soon (still figuring out which one will be hassle-free for me, and accessible to non-CNC people at the same time - anyway, you can count on some variant of vector graphic, for sure. SVG should be safe to declare as convertible to anything I'll decide on). I'll happily discuss details of personalization with everyone individually, so everyone can, always, ask me if some crazy idea is OK or a no-go. Apart from the points above, the only remaining rule is that implementing idea can't require enormous work from my side to apply it to the cover. All flat surfaces are "safe" to request engraved things on them. Curved ones not so, as it would require adding 3th dimension to engraving it, aka quite a hassle to implement - unless you grab sources from gitorious, fork, and code it yourself for 100% fit, then it can even be covered in 3D magic runes Summing it up, I will LOVE to personalize pieces for people that helped/are helping to make it happen. Just keep it sane /Estel
