I received mine too.

within 10 days from:
(aa) the date the Offer becomes or is declared unconditional, if the valid
acceptances are received during the period when the Offer is still conditional;
or
(bb) the date of the valid acceptances, if the valid acceptances are received during
the period after the Offer is or has become or has been declared unconditional.

As stated in the offer document, so, i believe Chin WH is right

I think you must sign the forms then either send by physical mail or via Boardroom. Accepting via BursaAnywhere is not available, at least for me.

Lex Q, the instructions are stated in appendix II of the offer document. You could accept the offer by following those instructions.

I got mine already, on last Friday night

I haven't receiced it also, guess rakuten operators are sleeping
