Dear colleague,

we would like to invite you to a common meeting of the LDC and the GLD concept groups at the American linear collider meeting, ALCPG, at Chicago in October. We plan to use both slots which have been provided by the organizers of the meeting, on Tuesday morning, and on Friday afternoon of the week. Plans are still evolving, but we anticipate the following program:

- Tuesday morning:
o presentation of the state of the cooperation
between LDC and GLD, presentation of work by the
different working groups
o Review of the current state of the two concepts
LDC and GLD
o Possibility (if time allows) for more specialised
contributions by members of LDC and GLD

- Friday afternoon: planning and discussion session:
o how do we continue, how do we make progress towards
an letter of intent, etc.

If you like to make a presentation at this meeting, please contact either ties.behnke@desy.de or yhitoshi@awa.tohoku.ac.jp
